This will give me about 10 amps of AC power without the on-board AC generator (the on-board generator pumps out 30 amps). While cruising, the Ford Triton V10 Alternator pumps out 70 amps DC so I have enough DC power to convert to AC power. When “Dry Camping” I can run the CPAP 8 hours since it only draws 25 watts, without drawing down the batteries too much.

Well...10 amps would be exceeding 1000 watts (1100-1200 depending on whether you consider it 110 or 120v).
Delivering 1000 watts with zero loss (not reality) would use 83amps... More than your alternators total output.
Most CPAPs, laptops... some TVs will run directly from 12v.
I added a 12v tv and Blu-ray for travel/boondocking.
That leaves the inverter to power the coffee maker... Plug it in to the inverter when needed, and no suicide cord for anyone to get hurt with...
(Yes I've done the backfeed at home for storms... Certainly the exception, and carefully controlled. I wouldn't do it as a 'normal' course of traveling...
Plug in the specific devices you need, wire it in with a switch like Tfryman did, or get one with an internal transfer switch...)
